As the title says, does anyone know of a PCIe x1 slot, 2.5GBe network card? I have found this Intel based I225-V 2.5Gbps Ethernet PCI Express Card RJ45 LAN Adapter Converter. Any other options or opinions? I don’t need a enterprise level of performance. Currently I have a vdev of 8 wide 3TB WD Reds with a 1GBe realtek NIC (built in). Hoping to get some better throughput. I am limited to x1 PCIe unfortunately however.
Any PCIe card that will physically fit in the slot should be compatible with x1 electrical, even if it’s x2 etc.
x1 at PCIe2 speed is good for about 500MB/s iirc, which means plenty for 2.5gbps.
And at PCIe3 speeds… about 1GB/s per lane.
I’d go with the intel adapter.
Actually, I’d go with an intel 550-T2 10gbe adapter.
But anyway.
Thanks for the reply. Yeah, I’d go for the 550-T2 but its nearly $300 more. Not worth it for my use case. A single 2.5GBe is plenty for my needs. Thanks again
Its 99$
Yeah, that’s $166 in my dollars mate. Still way too much as I need two of them and a switch for my setup.
I’m using an i226 pcie x1 based 2.5Gbe adapter on a smaller TrueNAS server, it has worked without issues and indeed it’s nice to not waste a bigger slot on a NIC (most pcie x1 slots don’t have the “open back” needed to fit a bigger card)
if you are buying a new card, buy the i226 and not the i225.

Hey mate!
If you’re running Core, these may not (indeed, probably won’t) work. If you’re feeling lucky you can give one or both a go and return the failures
If you’re running Scale, Amazon.com.au has 2 that should do the trick:
XikeStor 2.5Gb PCIe x1 NIC for A$60, search for its ASIN - B0CYB1GSHS
It claims to support Linux
BrosTrend 2.5GB Linux Compatible NIC for A$47 - B0C65SZG5M
Even PCIe 1.0 x1 should be able to get you 2.5Gbps, or close to it
Cheers,
Laz

Just noticed that the XikeStor NIC is an Intel i226-v, so that one might actually work with Core
